If you're looking to change your password manager, I've been using `pass` [0] for years now, and it's one of he best open source project I have ever used. Everything works, it uses git for remote storage and gpg for encryption.
There is no fancy browser plugin, but a command line to get the password is enough, since browsers cache the password afterwards and most sites use long lived sessions through cookies. And the android app works well.
Pass feels simple but it is actually elegant.
